PZ is adorably cutely awesome. He thinks most of his readers are full time workers works in office space.
I wouldn’t put the median age more than 21.

When I was 21, I was a full time worker in an office space. I’m not sure I see how statement relates to the other? I’m also not sure how the median tells us anything about where most of us are, since the median of {20,21, 21, 21, 21, 21, 21, 21, 21, 66, 6346098234594987345, 234346539847105987609234987193875394875} is 21. Did you mean the mean age?
